| Lepidine Usage And Synthesis |
| Description | Refer to 6-METHYLQUINOLINE. | | Chemical Properties | clear slightly yellow to brown liquid | | Uses | Lepidine is used in the preparation of certain dyes. | | Uses | 4-Methylquinoline is used as a reagent in the synthesis of azetidine based ene-amides as potent bacterial enoyl ACP reductase inhibitors. Also used as a reagent in the synthesis of cyanine-styryl dyes with enhanced photostability for fluorescent DNA imaging. | | Definition | ChEBI: A methylquinoline carrying a methyl substituent at position 4. | | Synthesis Reference(s) | Tetrahedron Letters, 28, p. 5291, 1987 DOI: 10.1016/S0040-4039(00)96710-8 | | General Description | Synthesis of lepidine from 4-anilinobutan-2-one in ethanol in the presence of HCl or FeCl3 has been reported. Nitration of lepidine has been reported. | | Purification Methods | Reflux lepidine with BaO, then fractionally distil it. Further purify it via its recrystallised dichromate salt (m 138o) (from H2O). [Cumper et al. J Chem Soc 1176 1962.] [Beilstein 20 III/IV 3477, 20/7 V 389.] |
